</span>I can't reproduce this. I've checked, there are only two places setting this<br>
variable, the only place it's used is passing it to the boyles_law().<br>
Printing it<br>
there gives the same value several times...<br></blockquote><div><br></div><div>My bad - I read the code incorrectly and the examples I tested gave the impression that it was run at every stop because there were 3m depth difference between the depth variable at the breakpoints.<br><br>Your explanation is correct - it was the different CVA iterations calculating different first stop depths. E.g. gdb output for a dive to 45m for 20min, breathing 18/45, with 50% and 100% deco gasses and zero conservatism:<br><br>
